This trial targeted to analyze the effects of different doses of tirofiban combined with dual antiplatelet drugs on platelet indices, vascular endothelial function, and major adverse cardiovascular events (MACE) in patients with acute ST-segment elevated myocardial infarction (STEMI) undergoing percutaneous coronary intervention (PCI). A total of 180 patients with STEMI who underwent PCI were divided into Group A, Group B, and Group C (60 cases per group). Group A was given conventional medication, and Groups B and C were given a standard dose (10 μg/kg) and a high dose (20 μg/kg) of tirofiban on the basis of Group A, respectively.

The role of serine/threonine protein kinases in cardiovascular disease and potential therapeutic methods.

Protein phosphorylation is an important link in a variety of signaling pathways, and most of the important life processes in cells involve protein phosphorylation. Based on the amino acid residues of phosphorylated proteins, protein kinases can be categorized into the following families: serine/threonine protein kinases, tyrosine-specific protein kinases, histidine-specific protein kinases, tryptophan kinases, and aspartate/glutamyl protein kinases. Of all the protein kinases, most are serine/threonine kinases, where serine/threonine protein kinases are protein kinases that catalyze the phosphorylation of serine or threonine residues on target proteins using ATP as a phosphate donor.

Objective: To evaluate such a multifaceted model with a more stringent blood pressure treatment goal (<130/80 mm Hg) among patients aged 60 years and older with hypertension.

Design, Setting, And Participants: This was a 48-month follow-up study of the China Rural Hypertension Control Project (CRHCP), an open-cluster randomized clinical trial, conducted from 2018 to 2023.

The phosphorylation-deubiquitination positive feedback loop of the CHK2-USP7 axis stabilizes p53 under oxidative stress.

p53 regulates multiple signaling pathways and maintains cell homeostasis under conditions of DNA damage and oxidative stress. Although USP7 has been shown to promote p53 stability via deubiquitination, the USP7-p53 activation mechanism has remained unclear. Here, we propose that DNA damage induces reactive oxygen species (ROS) production and activates ATM-CHK2, and CHK2 then phosphorylates USP7 at S168 and T231.

BAG3 promotes proliferation and migration of arterial smooth muscle cells by regulating STAT3 phosphorylation in diabetic vascular remodeling.

Background: Diabetic vascular remodeling is the most important pathological basis of diabetic cardiovascular complications. The accumulation of advanced glycation end products (AGEs) caused by elevated blood glucose promotes the proliferation and migration of vascular smooth muscle cells (VSMCs), leading to arterial wall thickening and ultimately vascular remodeling. Therefore, the excessive proliferation and migration of VSMCs is considered as an important therapeutic target for vascular remodeling in diabetes mellitus.

ATM-CHK2-TRIM32 axis regulates ATG7 ubiquitination to initiate autophagy under oxidative stress.

Oxidative stress-induced autophagy helps to prevent cellular damage and to maintain homeostasis. However, the regulatory pathway that initiates autophagy remains unclear. We previously showed that reactive oxygen species (ROS) function as signaling molecules to activate the ATM-CHK2 pathway and promote autophagy.

The role of glycolytic metabolic pathways in cardiovascular disease and potential therapeutic approaches.

Cardiovascular disease (CVD) is a major threat to human health, accounting for 46% of non-communicable disease deaths. Glycolysis is a conserved and rigorous biological process that breaks down glucose into pyruvate, and its primary function is to provide the body with the energy and intermediate products needed for life activities. The non-glycolytic actions of enzymes associated with the glycolytic pathway have long been found to be associated with the development of CVD, typically exemplified by metabolic remodeling in heart failure, which is a condition in which the heart exhibits a rapid adaptive response to hypoxic and hypoxic conditions, occurring early in the course of heart failure.

Although systematic reviews (SRs) and meta-analyses (Mas) of efficacy studies have been published, the results remain uncertain, and their quality has not yet been fully evaluated. Here, we summarize the existing SRs/Mas, evaluate their quality and level of evidence, and provide a reference for the effectiveness of TC.

Atorvastatin rescues vascular endothelial injury in hypertension by WWP2-mediated ubiquitination and degradation of ATP5A.

As a widely used lipid-lowering drug in clinical practice, atorvastatin is widely recognized for its role in protecting vascular endothelium in the cardiovascular system. However, a clear mechanistic understanding of its action is lacking. Here, we found that atorvastatin counteracted angiotensin II-induced vascular endothelial injury in mice with hypertension.

The role of SMURFs in non-cancerous diseases.

The ubiquitin-proteasome system is a crucial mechanism for regulating protein levels in cells, with substrate-specific E3 ubiquitin ligases serving as an integral component of this system. Among these ligases are SMAD-specific E3 ubiquitin-protein ligase 1 (SMURF1) and SMAD-specific E3 ubiquitin-protein ligase 2 (SMURF2), which belong to the neural precursor cell-expressed developmentally downregulated 4 (NEDD4) subfamily of Homologous to E6-AP COOH terminus (HECT)-type E3 ligases. As E3 ligases, SMURFs have critical functions in regulating the stability of multiple proteins, thereby maintaining physiological processes such as cell migration, proliferation, and apoptosis.
